Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming. [PDF]

Adv Sci (Weinh)
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Noise-Resilience Horizon of Groundwater Potential Maps Generated by Frequency-Ratio Data Integration

Frontiers in Environmental Science, 2020
The study of groundwater distribution is gaining importance due to the mounting pressures exerted by rapid urban growth on water supply, especially in small islands that could experience faster supply deterioration through saltwater intrusion ...

Valuing potential groundwater protection benefits

Water Resources Research, 1991
This paper explores the implications of endogenous risk for the economic value of preventing groundwater contamination. We consider the analytical implications of endogenous risk for five key building blocks frequently used to structure studies of groundwater valuation: the probability and the location of contamination, the exposed population, risk ...

Polyurethane-Degrading Potential of Alkaline Groundwater Bacteria

Microbial Ecology, 2023
Plastic waste is a global environmental burden and long-lasting plastic polymers, including ubiquitous and toxic polyurethanes (PUs), rapidly accumulate in the water environments. In this study, samples were collected from the three alkaline groundwater occurrences in the geotectonic regions of the Pannonian basin of northern Serbia (Torda and ...

Assessment of Potential Groundwater Resources for Optimal Management of Coastal Groundwater [PDF]

Journal of Korea Water Resources Association, 2007
An equation is developed to estimate potential groundwater resources available for development. This equation is useful for preliminary planning stages prior to detailed design stages. The equation is a function of major factors such as aquifer characteristics, saltwater intrusion length, coastal groundwater discharge and potential locations of pumping

Combined use of groundwater modeling and potential zone analysis for management of groundwater

International Journal of Applied Earth Observation and Geoinformation, 2011
A methodology for groundwater evaluation has been developed by the combined use of numerical model and spatial modeling using GIS. The developed methodology has been applied on the sub-basin of the Banganga River, India. Initially, the groundwater potential zones have been delineated by spatial modeling.

The potential for methane emissions from groundwaters of the UK [PDF]

Science of The Total Environment, 2005
Methane (CH4) is only a trace constituent of the atmosphere but an important greenhouse gas. Although groundwater is unlikely to be a major source of atmospheric CH4, its contribution to the CH4 budget of the UK has up to now been poorly characterised.
